Semiconductor device for pulling down output terminal voltage |
摘要 |
A semiconductor device, provided with a buffer, which comprises a first transistor for pulling up the output terminal voltage, a second transistor for pulling down the output terminal voltage, and a charge-pumping circuit for maintaining the output terminal voltage at a level higher than the power source voltage by charge pumping when the output terminal voltage is at a high level. The semiconductor device further comprises a circuit for pulling down the output terminal voltage during the period from when power is supplied to when an input signal is supplied to the buffer.
